Abstract

A highly efficient and highly controllable method and an apparatus for core-back injection molding of multi-component plastic products. Core-back injection molding makes possible the injection of a first plastic material into a mold cavity followed by retracting a barrier means (22, 26) in order to enable injection of a second plastic material without separating any mold halves.
The present invention enables very efficient injection molding because both injection units may be operated at the same time, and the present invention enables very controlled injection because it is possible to inject only one half of the cavities by a specific injection unit at the same time, or even only one quarter of the cavities by a specific injection unit at the same time. The injection molding apparatus includes a first injection unit, a second injection unit, a right adjustable mold cavity (20) with a first moveable barring means (22), a left adjustable meld cavity (24) with a second moveable barring means (26), and a common standard clamping unit (28).
